Title: Device for reading multichannel oscillograms
Inventor: CHEGOLIN PETR MIKHAILOVICH
IPC: G06K11/00
Filed: 1970-01-23
Abstract: 1294226 oscillogram curve reading INSTITUT TEKHNICHESKOI KIBERNETIKI 23 Jan 1970 3392/70 Heading G4H In a device for determining the ordinates of curves recorded on a multichannel oscillogram tape by periodically photo-electrically scanning across the moving tape and reading a clock driven counter as each curve is met, the sensitivity of the photo-electric scanning unit is automatically changed if the number of curves met is different from the number expected. In one arrangement, where only increases in sensitivity are possible, the number of curves met, held in a counter, is compared with the expected number held in a selector switch and if less there is an increase in one of a counter controlling via a decoder the scanning unit amplifier. The use of a reversible counter enabling decreases in sensitivity is mentioned. During a scan a counter counts the number of curves met and at each curve the state of a clockdriven counter, defining the ordinate of the curve, is read out into a buffer at an address defined by the state of the curve counter. At the end of a scan the ordinate counter is zeroized and each ordinate transmitted in turn out of the buffer via the ordinate counter to a computer. The data is followed by an end of data character and optionally preceded by a count of the number of timing reference marks so far reached. This reading out counts down the curve counter and on reaching zero sends an end of message signal and starts another scan. If the separation of any two curves is less than a selectable amount a so-called extrapolation signal is sent to the computer on a dedicated line at the same time as the ordinate data. The next scan is made a predetermined number of timing marks ahead, which number is automatically reduced to a lower number if this extrapolation signal is generated.

Title: Improvements in or relating to methods of and apparatus for measuring far-end crosstalk
IPC: H04B3/46
Filed: 1938-02-04
Abstract: 510,714. Telephone transmission measurements. STANDARD TELEPHONES & CABLES, Ltd., and FENNESSY, E. Feb. 4, 1938, No. 3581. [Class 37] Measurements of the characteristics of a transmission circuit at carrier or voice frequencies, for example, far-end cross-talk or attenuation, or of a network such as a filter, are effected at a given frequency that is reduced to a constant value at which measurement is made, the currents of given frequency being derived from the local oscillator of the detector-amplifier apparatus. Recording meters can be employed, the recording drum being connected with the condenser of the local oscillator and turned by hand. At voice frequencies, the measurements are effected by connecting in circuit a weighting network, and rapidly varying the frequency of the local oscillator throughout this range. For measuring far-end cross-talk, Fig. 2, the disturbing line or pair L<SP>1</SP> is supplied from the local oscillator 0 through a frequency changer FC located at the distant end, the output frequency of which is received on the coupled disturbed line or pair L, and beats with the higher frequency of the oscillator in modulator M from which, for example, a 1 kc. sideband is passed to the measuring instrument ME. A spare pair or line P can be used for transmitting the currents of given frequency to the disturbing line. The frequency reducer FC comprises apparatus, Fig. 3, producing a double modulation, and reduces any input thereto by 1 kc. For example, a frequency f from oscillator 0 is applied to modulator M<SP>1</SP> together with a frequency f<SP>3</SP>, the upper sideband being applied through filter HPF to modulator M<SP>2</SP> together with a frequency f<SP>4</SP>, f<SP>4</SP>-f<SP>3</SP> being equal to 1 kc. The lower sideband from this modulation is applied to the detector amplifier circuit through filter LPF, and, beating with the frequency f 2 , produces a lower sideband of 1 kc.
